This application claims priority to U.S. Provisional Application Nos. 63/334,026, filed on Apr. 22, 2022, and 63/334,031, filed on Apr. 22, 2022. These and all other extrinsic materials discussed herein, including publications, patent applications, and patents, are incorporated by reference in their entirety. Where a definition or use of a term in an incorporated reference is inconsistent or contrary to the definition of that term provided herein, the definition of that term provided herein applies and the definition of the term in the reference does not apply.

The field of the invention is trailers, and systems and methods for controlling trailers.

Hitching and unhitching trailers can be strenuous, time consuming, error prone, and risky and as we transition to electric vehicles there is the potential to need to hitch and unhitch trailers much more frequently so that the tow vehicle can fit into a charging stall to recharge (and recharging happens more frequently because of the reduced range when towing a trailer). This can become even less convenient during times of inclement weather.

Accordingly, self-hitching and parking trailers, and systems, methods, and non-transitory computer-readable media for controlling a trailer are provided herein.

According to one aspect, a system for controlling a trailer is provided, comprising one or more sensors configured to detect data associated with at least one of the trailer, a tow vehicle the trailer is configured to mechanically couple to, and an area surrounding at least one of the trailer and the tow vehicle, and a controller, comprising one or more processors, and a memory storing software instructions that, when executed by the one or more processors, cause the one or more processors to: obtain the sensor data from the one or more sensors; obtain an indication of an event based at least in part on the sensor data; and initiate a mechanical coupling or decoupling of the trailer to the tow vehicle based at least in part on obtaining the indication of the event.

According to another aspect, a trailer configured to mechanically couple to a tow vehicle is provided, comprising a powering system, a steering system, a hitching system, and a controller operably coupled to the powering system, the steering system and the hitching system for at least one of unhitching, hitching and parking the trailer. In some embodiments, the trailer does not comprise a driver and/or passenger seat and is configured to be driven by a user that is not in/on the trailer.

In another aspect, a trailer configured to couple to a tow vehicle having a hitch with at least a first opening (e.g., first and second openings) is provided, comprising a coupling device, the coupling device comprising: a first portion coupled to (or configured to couple to) the trailer, a second portion coupled to the first portion via a first joint, a third portion coupled to the second portion via a second joint, the third portion having an end portion sized and dimensioned to be received by the hitch of the tow vehicle. In some embodiments, the end portion comprises first and second pins configured to extend through the first and second openings to secure the coupling device to the tow truck. In some embodiments, the first and second joints each provide pitch, and only the second joint provides roll. In some embodiments, each of the first, second, and third portions are straight/linear. In some embodiments, the first and/or second joints are universal joints. In some embodiments, the first, second and third portions each comprise a single piece. In some embodiments, the coupling devices can comprise any suitable number of portions (e.g., 2, 3, 4, 5) and/or joints (e.g., 1, 2, 3, 4, 5). In some embodiments, each of the portions can comprise a single piece (e.g., other than retractable pins). It should be appreciated that when two physical components are described herein as being “coupled to” one another, such term is intended to include both direct coupling (in which two elements that are coupled to each other contact each other) and indirect coupling (in which at least one additional element is between the two elements) unless the context dictates otherwise.

In another aspect, a system for controlling a trailer is provided, comprising one or more sensors configured to detect data associated with at least one of the trailer, a tow vehicle the trailer is configured to mechanically couple to, and an area surrounding at least one of the trailer and the tow vehicle (e.g., roads, ground the tires are on/navigating, lots, area immediately surrounding the vehicle), and a controller, comprising: one or more processors; and a memory storing software instructions that, when executed by the one or more processors, cause the one or more processors to: obtain the sensor data from the one or more sensors, identify an event associated with at least one of the trailer, the tow vehicle and the area surrounding at least one of the trailer and the tow vehicle based at least in part on the sensor data, and initiate an action related to at least one component of the trailer based at least in part on identifying the event.

In another aspect, a non-transitory computer readable medium having instructions stored therein is provided, wherein the instructions, when executed by a processor, cause the processor to: obtain the sensor data from one or more sensors coupled to at least one of a tow vehicle and a trailer configured to couple to the tow vehicle, obtain an indication of an event associated with at least one of the trailer, the tow vehicle and the area surrounding at least one of the trailer and the tow vehicle based at least in part on the sensor data, and initiate an action related to at least one component of the trailer based at least in part on identifying the event.

In another aspect, a method is provided, comprising using at least one hardware processor to obtain sensor data from one or more sensors coupled to at least one of a tow vehicle and a trailer configured to couple to the tow vehicle, obtain an indication of an event associated with at least one of the trailer, the tow vehicle and the area surrounding at least one of the trailer and the tow vehicle based at least in part on the sensor data, and initiate an action related to at least one component of the trailer based at least in part on identifying the event.

Other advantages and benefits of the disclosed system and methods will be apparent to one of ordinary skill with a review of the following detailed description.

In an embodiment, systems, methods, and non-transitory computer-readable media are disclosed for controlling a trailer, for example, for parking a trailer, steering a trailer, and hitching or unhitching a trailer to a tow vehicle. Sensors and AI/ML algorithms can be used to obtain an indication of an event, and optionally to initiate an action associated with the trailer.

After reading this description, it will become apparent to one skilled in the art how to implement the invention in various alternative embodiments and alternative applications. However, although various embodiments of the present invention will be described herein, it is understood that these embodiments are presented by way of example and illustration only, and not limitation. As such, this detailed description of various embodiments should not be construed to limit the scope or breadth of the present invention as set forth in the appended claims. In some instances, well-known structures and components are shown in simplified form for brevity of description. Some of the surfaces have been left out or exaggerated for clarity and ease of explanation.

1 FIG. 110 110 110 112 114 110 130 120 110 140 120 illustrates an example infrastructure in which one or more of the disclosed processes may be implemented, according to an embodiment. The infrastructure may comprise a platform(e.g., one or more servers) which hosts and/or executes one or more of the various functions, processes, methods, and/or software modules described herein. Platformmay comprise dedicated servers, or may instead comprise cloud instances, which utilize shared resources of one or more servers. These servers or cloud instances may be collocated and/or geographically distributed. Platformmay also comprise or be communicatively connected to a server applicationand/or one or more databases. In addition, platformmay be communicatively connected to one or more user systemsvia one or more networks, or may be entirely implemented on the loopback (e.g., localhost) interface. Platformmay also be communicatively connected to one or more external systems(e.g., other platforms, websites, etc.) via one or more networks.

120 110 130 110 120 110 110 130 140 130 140 130 140 112 114 110 130 140 Network(s)may comprise the Internet, and platformmay communicate with user system(s)through the Internet using standard transmission protocols, such as HyperText Transfer Protocol (HTTP), HTTP Secure (HTTPS), File Transfer Protocol (FTP), FTP Secure (FTPS), Secure Shell FTP (SFTP), and the like, as well as proprietary protocols. While platformis illustrated as being connected to various systems through a single set of network(s), it should be understood that platformmay be connected to the various systems via different sets of one or more networks. For example, platformmay be connected to a subset of user systemsand/or external systemsvia the Internet, but may be connected to one or more other user systemsand/or external systemsvia an intranet. Furthermore, while only a few user systemsand external systems, one server application, and one set of database(s)are illustrated, it should be understood that the infrastructure may comprise any number of user systems, external systems, server applications, and databases. In addition, communication between any of these systems, for example, platform, user systems, and/or external system, may be entirely implemented on the loopback (e.g., localhost) interface.

130 130 132 134 130 110 120 130 132 110 User system(s)may comprise any type or types of computing devices capable of wired and/or wireless communication, including without limitation, desktop computers, laptop computers, tablet computers, smart phones or other mobile phones, servers, game consoles, televisions, set-top boxes, electronic kiosks, point-of-sale terminals, and/or the like. Each user systemmay comprise or be communicatively connected to a client applicationand/or one or more local databases. While user systemand platformare shown here as separate devices connected by a network, user systemmay comprise an applicationthat may comprise one portion of a distributed cloud-based system that integrates with platform, for example, using a multi-tasking OS (e.g., Linux) and local only (localhost) network addresses.

110 110 130 130 110 110 120 114 110 110 130 Platformmay comprise web servers which host one or more websites and/or web services. In embodiments in which a website is provided, the website may comprise a graphical user interface, including, for example, one or more screens (e.g., webpages) generated in HyperText Markup Language (HTML) or other language. Platformtransmits or serves one or more screens of the graphical user interface in response to requests from user system(s). In some embodiments, these screens may be served in the form of a wizard, in which case two or more screens may be served in a sequential manner, and one or more of the sequential screens may depend on an interaction of the user or user systemwith one or more preceding screens. The requests to platformand the responses from platform, including the screens of the graphical user interface, may both be communicated through network(s), which may include the Internet, or may be entirely implemented on the loopback (e.g., localhost) interface, using standard communication protocols (e.g., HTTP, HTTPS, etc.). These screens (e.g., webpages) may comprise a combination of content and elements, such as text, images, videos, animations, references (e.g., hyperlinks), frames, inputs (e.g., textboxes, text areas, checkboxes, radio buttons, drop-down menus, buttons, forms, etc.), scripts (e.g., JavaScript), and the like, including elements comprising or derived from data stored in one or more databases (e.g., database(s)) that are locally and/or remotely accessible to platform. Platformmay also respond to other requests from user system(s).

110 114 110 114 112 110 132 130 114 114 110 112 110 Platformmay comprise, be communicatively coupled with, or otherwise have access to one or more database(s). For example, platformmay comprise one or more database servers which manage one or more databases. Server applicationexecuting on platformand/or client applicationexecuting on user systemmay submit data (e.g., user data, form data, etc.) to be stored in database(s), and/or request access to data stored in database(s). Any suitable database may be utilized, including without limitation MySQL™, Oracle™, IBM™, Microsoft SQL™, Access™, PostgreSQL™, MongoDB™, and the like, including cloud-based databases and proprietary databases. Data may be sent to platform, for instance, using the well-known POST, GET, and PUT request supported by HTTP, via FTP, proprietary protocols, requests using data encryption via SSL (HTTPS requests), and/or the like. This data, as well as other requests, may be handled, for example, by server-side web technology, such as a servlet or other software module (e.g., comprised in server application), executed by platform.

110 140 110 130 140 130 140 132 130 112 110 132 134 130 In embodiments in which a web service is provided, platformmay receive requests from external system(s), and provide responses in eXtensible Markup Language (XML), JavaScript Object Notation (JSON), and/or any other suitable or desired format. In such embodiments, platformmay provide an application programming interface (API) which defines the manner in which user system(s)and/or external system(s)may interact with the web service. Thus, user system(s)and/or external system(s)(which may themselves be servers), can define their own user interfaces, and rely on the web service to implement or otherwise provide the backend processes, methods, functionality, storage, and/or the like, described herein. For example, in such an embodiment, a client application, executing on one or more user system(s), may interact with a server applicationexecuting on platformto execute one or more or a portion of one or more of the various functions, processes, methods, and/or software modules described herein. In an embodiment, client applicationmay utilize a local databasefor storing data locally on user system.

132 112 110 132 130 112 110 130 132 112 110 110 112 130 132 110 130 112 132 Client applicationmay be “thin,” in which case processing is primarily carried out server-side by server applicationon platform. A basic example of a thin client applicationis a browser application, which simply requests, receives, and renders webpages at user system(s), while server applicationon platformis responsible for generating the webpages and managing database functions. Alternatively, the client application may be “thick,” in which case processing is primarily carried out client-side by user system(s). It should be understood that client applicationmay perform an amount of processing, relative to server applicationon platform, at any point along this spectrum between “thin” and “thick,” depending on the design goals of the particular implementation. In any case, the software described herein, which may wholly reside on either platform(e.g., in which case server applicationperforms all processing) or user system(s)(e.g., in which case client applicationperforms all processing) or be distributed between platformand user system(s)(e.g., in which case server applicationand client applicationboth perform processing), can comprise one or more executable software modules comprising instructions that implement one or more of the processes, methods, or functions described herein.

110 130 140 120 110 130 140 110 130 140 While platform, user systems, and external systemsare shown as separate devices communicatively coupled by network, each of the devices shown as platform, user systems, and external systemsmay be implemented on one or more devices, and/or one or more of platform, user systems, and external systemsmay be implemented on a single device.

220 200 240 245 200 245 In alternative embodiments, secondary memorymay include other similar means for allowing computer programs or other data or instructions to be loaded into system. Such means may include, for example, a communication interface, which allows software and data to be transferred from external storage mediumto system. Examples of external storage mediuminclude an external hard disk drive, an external optical drive, an external magneto-optical drive, and/or the like.

200 240 240 200 200 110 240 240 200 120 240 As mentioned above, systemmay include a communication interface. Communication interfaceallows software and data to be transferred between systemand external devices (e.g. printers), networks, or other information sources.

240 255 255 240 250 250 120 250 255 Software and data transferred via communication interfaceare generally in the form of electrical communication signals. These signalsmay be provided to communication interfacevia a communication channel. In an embodiment, communication channelmay be a wired or wireless network (e.g., network(s)), or any variety of other communication links. Communication channelcarries signalsand can be implemented using a variety of wired or wireless communication means including wire or cable, fiber optics, conventional phone line, cellular phone link, wireless data communication link, radio frequency (“RF”) link, or infrared link, just to name a few.

215 220 240 215 220 200 Computer-executable code (e.g., computer programs, such as the disclosed software) is stored in main memoryand/or secondary memory. Computer-executable code can also be received via communication interfaceand stored in main memoryand/or secondary memory. Such computer programs, when executed, enable systemto perform the various functions of the disclosed embodiments as described elsewhere herein.

200 215 220 225 230 245 240 200 In this description, the term “computer-readable medium” is used to refer to any non-transitory computer-readable storage media used to provide computer-executable code and/or other data to or within system. Examples of such media include main memory, secondary memory(including internal memory, removable medium, and external storage medium), and any peripheral device communicatively coupled with communication interface(including a network information server or other network device). These non-transitory computer-readable media are means for providing software and/or other data to system.

200 230 235 240 200 255 210 210 In an embodiment that is implemented using software, the software may be stored on a computer-readable medium and loaded into systemby way of removable medium, I/O interface, or communication interface. In such an embodiment, the software is loaded into systemin the form of electrical communication signals. The software, when executed by processor, preferably causes processorto perform one or more of the processes and functions described elsewhere herein.

200 235 235 200 Systemmay comprise an I/O interface. In an embodiment, I/O interfaceprovides an interface between one or more components of systemand one or more input and/or output devices. Example input devices include, without limitation, sensors, keyboards, touch screens or other touch-sensitive devices, cameras, biometric sensing devices, computer mice, trackballs, pen-based pointing devices, and/or the like. Examples of output devices include, without limitation, other processing devices, cathode ray tubes (CRTs), plasma displays, light-emitting diode (LED) displays, liquid crystal displays (LCDs), printers, vacuum fluorescent displays (VFDs), surface-conduction electron-emitter displays (SEDs), field emission displays (FEDs), and/or the like. In some cases, an input and output device may be combined, such as in the case of a touch panel display (e.g., in a smartphone, tablet, or other mobile device).

200 130 270 265 260 200 270 265 Systemmay also include optional wireless communication components that facilitate wireless communication over a voice network and/or a data network (e.g., in the case of user system). The wireless communication components may comprise an antenna system, a radio system, and a baseband system. In system, radio frequency (RF) signals are transmitted and received over the air by antenna systemunder the management of radio system.

270 270 265 In an embodiment, antenna systemmay comprise one or more antennae and one or more multiplexors (not shown) that perform a switching function to provide antenna systemwith transmit and receive signal paths. In the receive path, received RF signals can be coupled from a multiplexor to a low noise amplifier (not shown) that amplifies the received RF signal and sends the amplified signal to radio system.

265 265 265 260 In an alternative embodiment, radio systemmay comprise one or more radios that are configured to communicate over various frequencies. In an embodiment, radio systemmay combine a demodulator (not shown) and modulator (not shown) in one integrated circuit (IC). The demodulator and modulator can also be separate components. In the incoming path, the demodulator strips away the RF carrier signal leaving a baseband receive audio signal, which is sent from radio systemto baseband system.

260 260 260 260 265 270 270 If the received signal contains audio information, then baseband systemdecodes the signal and converts it to an analog signal. Then the signal is amplified and sent to a speaker. Baseband systemalso receives analog audio signals from a microphone. These analog audio signals are converted to digital signals and encoded by baseband system. Baseband systemalso encodes the digital signals for transmission and generates a baseband transmit audio signal that is routed to the modulator portion of radio system. The modulator mixes the baseband transmit audio signal with an RF carrier signal, generating an RF transmit signal that is routed to antenna systemand may pass through a power amplifier (not shown). The power amplifier amplifies the RF transmit signal and routes it to antenna system, where the signal is switched to the antenna port for transmission.

260 210 210 215 220 210 215 220 260 210 220 200 Baseband systemis also communicatively coupled with processor(s). Processor(s)may have access to data storage areasand. Processor(s)are preferably configured to execute instructions (i.e., computer programs, such as the disclosed software) that can be stored in main memoryor secondary memory. Computer programs can also be received from baseband processorand stored in main memoryor in secondary memory, or executed upon receipt. Such computer programs, when executed, can enable systemto perform the various functions of the disclosed embodiments.

210 112 132 112 132 110 130 110 130 110 130 210 210 Embodiments of processes for controlling components of a trailer will now be described in detail. It should be understood that the described processes may be embodied in one or more software modules that are executed by one or more hardware processors (e.g., processor), for example, as a software application (e.g., server application, client application, and/or a distributed application comprising both server applicationand client application), which may be executed wholly by processor(s) of platform, wholly by processor(s) of user system(s), or may be distributed across platformand user system(s), such that some portions or modules of the software application are executed by platformand other portions or modules of the software application are executed by user system(s). The described processes may be implemented as instructions represented in source code, object code, and/or machine code. These instructions may be executed directly by hardware processor(s), or alternatively, may be executed by a virtual machine operating between the object code and hardware processor(s). In addition, the disclosed software may be built upon or interfaced with one or more existing systems.

Alternatively, the described processes may be implemented as a hardware component (e.g., general-purpose processor, integrated circuit (IC), application-specific integrated circuit (ASIC), digital signal processor (DSP), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, etc.), combination of hardware components, or combination of hardware and software components. To clearly illustrate the interchangeability of hardware and software, various illustrative components, blocks, modules, circuits, and steps are described herein generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. Skilled persons can implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the invention. In addition, the grouping of functions within a component, block, module, circuit, or step is for ease of description. Specific functions or steps can be moved from one component, block, module, circuit, or step to another without departing from the invention.

Furthermore, while the processes, described herein, are illustrated with a certain arrangement and ordering of subprocesses, each process may be implemented with fewer, more, or different subprocesses and a different arrangement and/or ordering of subprocesses. In addition, it should be understood that any subprocess, which does not depend on the completion of another subprocess, may be executed before, after, or in parallel with that other independent subprocess, even if the subprocesses are described or illustrated in a particular order.

Trailers (e.g., nonautomotive vehicle, transport container, vehicle designed to serve as a temporary dwelling or place of business that are configured to be towed by a vehicle) are generally manually hitched to and unhitched from a tow vehicle, and rely on the tow vehicle to move—generally in the same direction as the tow vehicle. Further, known trailers are connected to a tow vehicle via wires to control certain components of the trailer (e.g., brake lights, turn signals, brakes).

The trailers, systems, methods and non-transitory computer readable media described herein can advantageously eliminate or reduce the need for a physical connection (e.g., other than to physically hitch the trailer to the tow vehicle), and can instead use sensors and artificial intelligence to determine when to use brake lights, turn signals, brakes, and other components of the trailer. A controller can be provided and operably coupled to the components to control the trailer (e.g., to turn a signal on and off, apply and release brakes). In some aspects, artificial intelligence, deep learning and machine learning technology can be utilized to ensure appropriate actions are taken (e.g., brake lights used, turn signal on/off, steer, speed up, slow down) and to continuously improve the trailers and systems described herein. For example, it is contemplated that a platform can obtain data from multiple sensors, user systems and external systems, and machine learning can be used to study the data, recognize patterns and correlations, and continuously improve the trailers and systems.

To build a reliable machine learning model, datasets can be divided into a training dataset and validation dataset. Training data is the set of data that is used to train and make the model learn features/patterns in the data. Training data can build up the machine learning algorithm. The algorithm can be fed input data, which corresponds to an expected output. The model can evaluate the data repeatedly to learn more about the data's behavior and adjusts to serve its intended purpose. The training data can be fed to the neural network repeatedly, and the model can continue to learn the features of the data. The validation set can comprise a set of data, separate from the training set, that is used to validate the model performance during training. The validation process can give information that helps determine whether the training is moving in the right direction or not (how well the model makes predictions). The model can be trained on the training set, and simultaneously, the model evaluation can be performed on the validation set.

In an aspect of the disclosure, the systems, methods and non-transitory computer readable media described herein can be used to cause a trailer to accelerate, for example, if the trailer has its own propulsion system. The propulsion system can comprise any suitable components to provide powered motion for the trailer (e.g., one or more transmissions, one or more sets of wheels (e.g., 1, 2, or more wheels), one or more engines, one or more motors, and/or one or more energy sources to power the engine or motor (e.g., fuel, batteries, electric power sources, solar panels, and/or any other suitable energy sources). In some aspects, the systems, methods and non-transitory computer readable media described herein can be used to control the steering of the trailer, for example, if the trailer has steerable wheels and/or a steering system. In some aspects, a system of the disclosure can be used to activate regenerative braking if that feature is incorporated into the trailer. In some aspects, the systems, methods and non-transitory computer readable media described herein can utilize wireless communication between the tow vehicle and the trailer to share information.

The trailers described herein can advantageously have their own means of propulsion and steering, and can comprise sensors and artificial intelligence combined with a user interface that enables a person to direct the trailer to, for example, unhitch itself from the tow vehicle, proceed to a designated parking space, proceed to a location of the tow vehicle, and hitch itself to the tow vehicle.

Such a trailer can make charging an electric vehicle easier as a person can remotely detach the trailer and have it park itself while they proceed to a separate parking space to change the vehicle (since most vehicle chargers are not designed to accommodate a trailer). Such a trailer can also make filling up a gas tank easier, and can be a useful feature when parking a trailer (e.g., at home for storage, at an RV park, or an RV storage lot).

Further, it is contemplated that the vehicle could change lanes as if the driver were driving a sports car with no (or substantially reduced) fishtailing and no (or significantly reduced) chance of jack-knifing. Still further, steerable trailer wheels could make it simple to parallel park or make a U turn or back out of a tight spot that normally wouldn't allow for that. Viewed from another perspective, the steerable trailer wheels could allow a person with no experience towing a trailer to tow like a professional, and make it possible for the trailer to maneuver (e.g., to park and/or navigate towards a tow vehicle) on its own when not connected to a vehicle. For example, is a user wants to charge an electric pickup but the cable cannot reach with the trailer attached, the trailer could be instructed to detach and find a parking place so the pickup can be charged.

The systems, methods, and non-transitory computer readable media described herein can advantageously allow a trailer to unhitch itself and find a parking space when it reaches its destination and/or when the tow vehicle needs to stop for a charge, and then autonomously hitch itself to the correct tow vehicle when requested. This can be done, for example, by utilizing AI (artificial intelligence); various sensors including optical, force, accelerometers, GPS (global positioning system), radar, lidar, and/or ultrasonic. The AI processor, for example, could comprise an NVIDIA Jetson robotics computer. The sensors can be used to determine where the trailer is, where the tow vehicle is, where open parking or charging spaces are, etc. The AI and sensors can be used to adjust the height, approach angle, alignment, and otherwise guide the trailer into the hitch on the tow vehicle. These same sensors can be used in combination with, or in place of, sensors or radios such as Bluetooth for tracking. For example, Bluetooth and ultrasonic sensors are both engineered to provide very accurate distance and position measurements. In some embodiments, the trailer could use optical sensors (cameras) positioned on each of the sides of the trailer and potentially on the tongue of the trailer to surveil its surroundings. An AI model could then use one or more neural networks to understand the environment, identify potential parking or charging spaces, identifying the tow vehicle (including through license plate recognition or other identifiers). Using the sensors and compute capability described herein can eliminate the need for a traditional 4 pin or 7 pin trailer wiring harness to connect the park/brake/signal lights and for braking so the driver of the tow vehicle would no longer need to exit the vehicle to disconnect or connect the wiring connections in order to unhitch or hitch a trailer respectively.

The trailer lights, brakes, and steering (by steerable wheels and/or by torque vectoring of drive wheels that are not steerable) can all be controlled without wired connections using a computing device (e.g. controller)/AI processor onboard the trailer. The commands to the trailer to hitch or unhitch can be given from an application on a computing device (e.g., a mobile device, vehicle infotainment system), through a dedicated wireless switch such as a Bluetooth button, and/or even potentially through gestures such as hand signals that are viewed by the trailer's sensors (e.g., image sensors, motion detectors), and/or voice controls that are provided to the trailer via integrated microphones or relayed from a mobile device or the tow vehicle's microphones. In some embodiments, autonomous movement could be safeguarded by requiring a user to hold down, for example, a virtual button on a mobile device or a physical button on a Bluetooth device, and/or though voice control/verbal cue that could be as simple as saying “STOP!” and/or automatically stopping for loud noises (e.g., when a honk is detected via one or more sensors), or through integration with the tow vehicle's infotainment system. Additionally or alternatively, the operator can simply direct the trailer using remote controls or by dragging and dropping an outline or other representation of the trailer onto the map (e.g., via the vehicle infotainment system) where the operator wants the trailer to go (such as into a parking space).

In some aspects, a trailer having a steering system including steerable wheels is provided, which can be controlled by a controller. In some embodiments, the trailer can have multiple (e.g., 4) independently-actuated wheels. In some aspects, steerable trailer wheels are provided, wherein the wheels can be configured to be steered and act like another set of wheels that rotate in relation to the vehicle. It is contemplated that the steerable wheels can make towing a trailer much safer, making it virtually impossible for the trailer to rollover. All suitable trailers are contemplated herein, including those described in Applicant's U.S. patent application Ser. No. 18/137,821 filed on Apr. 21, 2023, which is incorporated herein in its entirety.

According to one aspect, a system for controlling a trailer is provided, comprising one or more sensors configured to detect data associated with at least one of the trailer, a tow vehicle the trailer is configured to mechanically couple to, and an area surrounding at least one of the trailer and the tow vehicle, and a controller, comprising one or more processors, and a memory storing software instructions that, when executed by the one or more processors, cause the one or more processors to: obtain the sensor data from the one or more sensors; obtain an indication of an event based at least in part on the sensor data; and initiate a mechanical coupling or decoupling of the trailer to the tow vehicle based at least in part on obtaining the indication of the event.

In some embodiments, the computing device can be on the tow vehicle (e.g., part of an infotainment system of the tow vehicle), a mobile phone, tablet or computer, or any other suitable computing device. Computing device can communicate with controller directly (e.g., via Bluetooth, WiFi) with or without a network. Controller can receive a machine learning model and/or correlation data from computing device and initiate an action based at least in part on the machine learning model and/or correlation data. In some embodiments, the software instructions, when executed by the one or more processors, further cause the one or more processors to initiate an action related to at least one component of the trailer based at least in part on identifying the event. The action could comprise, for example, activating and/or releasing/deactivating a brake, activating or deactivating a brake light, activating a turn signal, deactivating a turn signal, activating emergency flashing lights, deactivating emergency flashing lights, powering a motor and/or engine of the trailer, steering one or more wheels, accelerating, decelerating, hitching the trailer to the tow vehicle, unhitching the trailer from the tow vehicle, powering on the trailer, powering off the trailer, parking the trailer, propelling the trailer to a destination, moving the trailer, and/or any other suitable action. In some embodiments, the action comprises at least one of an adjustment to a power system of the trailer, adjustment to a braking system of the trailer, adjustment to a steering system of the trailer, adjustment to a lighting system of the trailer, adjustment to a propulsion system of the trailer, an adjustment to a suspension system of the trailer, and an adjustment to a hitching system of the trailer.

200 200 As an example, controller (which can comprise a system) can be directly coupled to a computing device (which can comprise a second system) via Bluetooth, WiFi, antenna, etc. In an embodiment, the one or more processors can obtain sensor data indicative of the tow vehicle parking in a destination (e.g., image data, video data, GPS data, audio data), obtain an indication that the tow vehicle is ready for the trailer to de-couple from the tow vehicle (e.g., mechanically unhitch), and initiate a de-coupling/unhitching of the trailer from the tow vehicle and/or other action based at least in part on obtaining the indication. Obtaining the indication can comprise identifying the tow vehicle is headed for a parking destination, and/or transmitting the sensor data to a computing device and receiving the indication (e.g., after the computing device queries one or more databases storing correlation data and/or any other suitable data). For example, the correlation data could comprise a correlation between image/video data of a tow vehicle turning towards and/or stopped near (e.g., with a turn signal on) a parking space that is under a threshold size relative to the tow vehicle, and a need to unhitch the trailer from the tow vehicle. Initiating the de-coupling unhitching can comprise unlocking a coupling device from a trailer hitch, for example, by causing retractable pins of a locking mechanism of the coupling device to retract such that the coupling device, while remaining on the trailer, is no longer secured to the trailer hitch. In some embodiments, sensor data can comprise image/video/light data of an open second destination, an indication that be indicative of an open parking space sized and dimensioned to fit the trailer, and initiating an action can comprise activation of a propulsion, steering, navigation and/or other system of the trailer, for example, to cause the trailer to navigate and park in the open second destination (e.g., after unhitching). In some embodiments, sensor data can comprise data associated with a height of a tow vehicle and data associated with a height of a trailer, the sensor data and/or a notification associated with the sensor data (e.g., that the tow vehicle hitch is higher off the ground than a coupling device of the trailer) can be sent to computing device, and the computing device can present a user with the sensor data/notification via a user interface (e.g., a sound, text and/or images on a display), receive an input (e.g., a user input, for example, from a driver of the tow vehicle) via the user interface, and transmit instructions to the controller to adjust a height of a suspension system and/or component of the trailer.

In some embodiments, a user of a user systemcan access platform(e.g., via a login after creating an account), and communicate instructions, commands, data and/or other inputs, for example, related to a trailer, a tow vehicle, and/or an environment around the trailer/tow vehicle. The platform can communicate with external system(e.g., a controller onboard the trailer) and cause an action on the trailer (e.g., a hitching, unhitching, parking, navigating from a parking spot to the tow vehicle), for example, based on inputs from user system. In some embodiments, one or more user systemsand/or external systemscan transmit inputs and/or outputs to platform. Platformcan comprise or be communicatively coupled with one or more databases that can store the inputs and/or outputs and/or correlations between the inputs and outputs.

In some embodiments, a trailer does not require full autonomy, and is controlled in part based on input from a driver/passenger of a tow vehicle that the trailer is physically tethered to, for example, input of the driver/passenger via an interface coupled to and/or presented by infotainment system of the tow vehicle and/or a mobile phone.

Viewed from another perspective, the trailer can be configured to perform all parking, hitching, and unhitching functions without a driver or passenger. The braking system can comprise any components useful to decelerate the trailer. The powering (or propulsion/propelling) system can comprise any components useful for powered motion of the trailer, for example, a motor and/or engine, an energy source (e.g., fuel, battery, gasoline, diesel, propane, solar panels, electrical power sources, and/or any other suitable energy sources) to power the engine/motor, a transmission (e.g., elements operable to transmit mechanical power from the engine and/or motor to the wheels, gearbox, clutch, differential, and/or drive shaft), and/or wheels. The steering system can comprise any components useful to steer the trailer (e.g., steerable wheels, steering unit comprising any components operable to adjust the heading of the trailer). The hitching system can comprise any components useful to hitch the trailer to a vehicle, including, for example, an actuator coupled to an engagement and/or locking mechanism that engages/locks a trailer coupling device to a tow vehicle hitch, and/or a height adjustable suspension system that is configured to raise/lower the trailer or portion thereof to align the coupling device to the hitch. The trailer may also comprise a sensing system comprising one or more sensors (e.g., image sensors, accelerometers, height sensors, brake sensor, steering sensor) as described herein. The trailer may also comprise a lighting system comprising one or more lights and switches/components for causing a light to turn on, off, flash, etc.

In some embodiments, a trailer can comprise any suitable components such that the trailer can park, mechanically hitch to a tow vehicle and/or mechanically unhitch from a tow vehicle via a controller operably connected to such components. Some contemplated trailers can comprise components of cars and trucks, for example, components described in U.S. Pat. No. 11,203,337, which is incorporated by reference in its entirety.

In some embodiments, the controller comprises at least one hardware processor, a communication interface, and one or more software modules that are configured to, when executed by the at least one hardware processor, cause the one or more processors to receive an input from a computing device. In some embodiments, the one or more software modules, when executed by the at least one processor, cause the one or more processors to initiate an action related to at least one of the powering system, the steering system and the hitching system of the trailer based at least in part on the input. In some embodiments, the trailer further comprises a sensing system comprising one or more sensors. In some embodiments, the controller can be configured to communicate with a computing device (e.g., a mobile device of a driver of the tow vehicle, an infotainment system of the tow vehicle), which can allow a driver and/or passenger of the tow vehicle to interact with the controller from within the tow vehicle.

In some embodiments, the controller comprises at least one hardware processor, a communication interface, and one or more software modules that are configured to, when executed by the at least one hardware processor, cause the one or more processors to obtain sensor data from at least one sensor of the sensing system, and initiate an action related to at least one of the powering system, the steering system and the hitching system of the trailer based at least in part on the sensor data. In some embodiments, the software modules are further configured to, when executed by the at least one hardware processor, cause the one or more processors to receive an input from a computing device, and wherein initiating the action is based at least in part on the input. In some embodiments, at least one sensor of the sensing system comprises at least one of an image sensor, a video sensor, an accelerometer, a force sensor, a distance sensor, a global positioning system (GPS) sensor, a radar sensor, a light detection and ranging (lidar) sensor, and an ultrasonic sensor. In some embodiments, the software modules are further configured to, when executed by the at least one hardware processor, identify an event based at least in part on the sensor data, and wherein initiating the action is based at least in part on identifying the event.

Another key element for self-hitching/self-unhitching is the ability to safely connect to the hitch of a tow vehicle. Traditionally this has been done with a ball type hitch that has not been improved in decades. The traditional coupling includes a trailer hitch, a receiver tube coupled to the trailer hitch, a ball mount extending at an angle between receiver tube and trailer ball, a trailer ball, a trailer coupler that attaches to trailer ball, safety chains, a hatch pin, and trailer wiring harness. A coupling device is provided herein that eliminates the trailer coupler, the trailer ball, the ball mount (also called a receiver or receiver hitch), the hitch pin, the safety chains, and the wiring harness and replaces them with one or more joints (e.g., articulating joint) on the trailer that connects directly into the receive tube and then sets its own pins when fully inserted to lock it into place. This can be visually verified, for example, from the cabin of the tow vehicle using the backup camera of the tow vehicle, or the hitch camera of the trailer displayed on either the vehicle's infotainment screen or on a mobile device screen using the trailer's app. In some embodiments, the coupling device eliminates the receiver and ball and instead interfaces directly with the hitch (e.g., via receiver) through an articulating joint that allows for roll and pitch but isolates yaw. This can reduce the forces being transferred from the tow vehicle to the trailer and from the trailer to the tow vehicle due to road irregularities, impacts, or roll overs. The joints contemplated herein can comprise any suitable joint, including for example, a large commercial vehicle driveline U-joint (e.g., Meritor Permalube™ RPL Heavy-Duty Driveline Series—see https://www.meritor.com/products/drivelines/rpl/).

In an aspect, a trailer configured to couple to a tow vehicle having a hitch with first and second openings is provided, comprising a coupling device, comprising: a first portion coupled to the trailer, a second portion coupled to the first portion via a first joint, a third portion coupled to the second portion via a second joint, and wherein the third portion comprises an end portion sized and dimensioned to be received directly by the hitch of the tow vehicle, the end portion comprising first and second pins configured to extend through the first and second openings to secure the coupling device to the tow truck. In some embodiments, the first and second pins can be retractable (e.g., spring loaded, retracted/extended via an actuator. In some embodiments, the first and second joints each provide pitch, and only the second joint provides roll. In some embodiments, the first and second joints can each comprise U joints.

However, since drivers don't always properly use, for example, turn signals, the trailer can also (e.g., via sensors and the controllers described herein) automatically engage the turn signals when it notices the tow vehicle initiating a turn or lane change regardless of whether the driver engages the tow vehicles' turn signal (or, indicator) lights.

The lights of the trailer and/or braking system can also be engaged for braking based on the tow vehicle's brake light activation or due to the accelerometer(s) coupled to the trailer sensing a decelerating force of a certain magnitude that is greater than the force of coasting.

In some aspects, a system is provided comprising at least one sensor configured to obtain sensor data associated with at least one of a trailer, a tow vehicle, and an area surrounding at least one of the trailer and the tow vehicle. The system can further comprise a processing system coupled with the at least one sensor and configured to communicate the sensor data, and a platform. The platform can comprise and/or access a database storing correlation data, an ML model, etc. The platform can further comprise an application coupled with the database and configured to receive the sensor data (e.g., from the processing system) and determine an event associated with at least one of the trailer, the tow vehicle and the area surrounding at least one of the trailer and the two vehicle based at least in part on the sensor data. In some aspects, the application can determine the event based at least in part on a query of a database storing correlation data, threshold data and/or any other suitable data. In some aspects, the application is further configured to at least one of transmit instructions to initiate/cause the trailer to take a first action based at least in part on determining the event.

The sensor data described herein can comprise any suitable data associated with the vehicle, trailer, and/or a surrounding. For example, sensor data can comprise, among other things, speed data, image data, video data, sound data, crowd data, data associated with an intersection, data associated with an intersection light, data associated with a movement of the vehicle, data associated with a tilt, data associated with a turn, data associated with a height, data associated with a parking space, charging space and/or other location, and/or data associated with a distance to another vehicle or object.

200 130 140 In some aspects, the platform can comprise system. In some aspects, the platform can further be configured to communicate with one or more systems, for example one or more user systemsand/or external systems. The user system can comprise, for example, an infotainment system of a tow vehicle and/or a mobile device of a driver/passenger of the tow vehicle. The external system can comprise, for example, a controller onboard the trailer.

In some aspects, an event can comprise a turn, a stop sign or red light, a change from a red light to a green light, or a green light to a red light, a direction, entering a parking lot, a step in a navigation route (e.g., turn, enter or exit a freeway), an accident, a stopped car, or any other suitable event.

The action can be any suitable action of the trailer, including for example, setting off an alarm, turning off an alarm, turning a turn signal on or off, applying or releasing a brake or brake light, accelerating a trailer, decelerating a trailer, steering a trailer, and/or collapsing and/or expanding a trailer (e.g., a collapsible trailer as described in U.S. patent application Ser. No. 17/714,948).

In some aspects, a system for trailer control is provided, comprising a user interface configured to receive an input associated with a destination (e.g., a trailer destination, a tow vehicle destination, a destination of a driver or user). The system can also include a controller, comprising one or more processors, and a memory storing software instructions that, when executed by the one or more processors, cause the one or more processors to cause a trailer to at least one of unhitch from the tow vehicle, hitch to the tow vehicle, and navigate to a destination. The user interface can be, for example, a part of the tow vehicle, the trailer, or a remote user system. In some aspects, at least one sensor is provided and configured to obtain sensor data associated with at least one of the trailer, the tow vehicle, the destination, and an area surrounding at least one of the trailer, the tow vehicle, and the destination. In some aspects, the software instructions, when executed by the one or more processors, further cause the one or more processors to obtain sensor data from the at least one sensor. In some aspects, one or more databases are provided, and the software instructions when executed by the one or more processors, further cause the one or more processors to obtain navigation data (e.g., navigation instructions, map data, distance data, traffic information) associated with the destination from the one or more databases.

In some aspects, the controller is configured to determine a suitable destination (e.g., parking space) based at least in part on the sensor data. In some aspects, the controller is configured to determine a suitable destination (e.g., parking space) based at least in part on the sensor data and a query of a database storing, for example, sensor data, event data, historic data, driver data, vehicle data, navigation data, trailer data, traffic data, threshold data, correlation data, and/or any other suitable data.
